MaMills
Released 27 October 2026 · PC · Casual, Indie, Strategy

The 3D four-in-a-row game I played with my grandmother - now in a digital form. You can outsmart the Machine across five difficulties, solve 40 one-solution puzzles, or challenge a friend on the couch, over LAN or with Steam Remote Play Together.
Story
MaMills is four-in-a-row in 3D: drop pieces onto vertical sticks, let gravity stack them, and line up four in any direction, even straight through the cube. Outsmart the Machine across five difficulties, solve 40 one-solution puzzles, or challenge a friend on the couch, over LAN or with Steam Remote Play Together. This game is a tribute to my late Grandmother (aka Mami ), who I used to play this game with. I loved it then, and I love it now; I hope you find some joy in it too! ❤️ Four-in-a-row, but the board goes up too MaMills is a calm, controller-first board game. You drop coloured cylinders onto a 4×4 grid of vertical sticks, gravity stacks them, and the first player to line up four wins. Because the pieces stack, every stick is also a column, every row of sticks is also a plane, and a line can run corner to corner straight through the cube. Sixteen sticks, sixty-four places, seventy-six ways to win. I learned it from my grandmother, Mami. It is an old rule set that people have played for generations. This is that game, made digital, with a clear layout to be comfortable to play. How a match goes Pick a stick, drop a cylinder. A beam and a ghost piece show exactly...
